First Genetically Modified Human Embryo Under Review 509
Wired is reporting that Cornell University researchers genetically modified a human embryo in 2007, but have only recently been gaining publicity as their work is being reviewed. "The research raises a number of thorny ethical questions. Though adding a fluorescent protein was merely a proof-of-principle step, scientists say that modified embryos could be used to research human diseases. They say embryos wouldn't be allowed to develop for more than a few weeks, much less implanted in a woman and brought to term."

There are *2* stages of development before the blob of a few hundred cells is considered an "embryo". First, there's the formation of the zygote after fertilization, and then there's the formation of the blastocyst. The blastocyst is basically a hollow fluid filled sphere consisting of an outer layer of trophoblast cells which eventually become the placenta and an inner blob of cells called the embryoblast which eventually forms the embryo after the blastocyst phase.
When talking of "embryos", scientists are usually talking about the extracted embryoblast cells which are pluripotent stem cells. These cells are *NOT* viable and are just that : cells -- they're not going to grow into a baby, or an "embryo" for that matter. Even I would be upset if it were found out that the real embryo, after the start of cell differentiation, had been tampered with.
To conclude, stem cells are not embryos -- they're just a multiplying blob of undifferentiated pluripotent Human cells and as such, they should be put in the same class as pond scum, although pond scum is actually far more highly developed -- the aforementioned stem cells cannot survive outside of a Petri dish (unless they're implanted into another nutrient source, such as the Human body for purposes of healing)
